Oncological monitoring after transanal total mesorectal excision (TaTME) for rectal neoplasia.

BACKGROUND: The surgical treatment of choice for rectal neoplasia is total mesorectal excision (TME). The transanal approach enables a better approach in male and obese patients and/or those with a narrow pelvis and in patients with small tumors. Short-term results are comparable with those for laparoscopy or the open approach, but the medium- and long-term oncological data are sparse. The aim of the present study was to evaluate our early experience with transanal TME (TaTME). METHODS: This was a retrospective study conducted on patients who underwent TaTME at our center between August 2013 and April 2017 with a follow-up ≥ 3 years. Histopathology, complications, mortality, neoplastic recurrence and disease-free survival were analyzed. RESULTS: One hundred patients (68 men and 32 women,, median age 66.8 years [range 29.6-91.2 years]) were included. There were 67 T3 cases (67%) with 74 N0 cases (74%), the mesorectal quality was graded optimal for 87.6% and only 2 cases of radial margin involvement were detected (2%). The median follow-up period was 47.6 months (range 11.8-78.9 months). Eighteen cases of recurrence were diagnosed, of which 3 (3%) recurred locally with an average disease-free period of 43.1 months. Overall survival was 80% and mortality due to progression of disease was 13%. CONCLUSIONS: TaTME is a safe surgical procedure with surgical, anatomopathological and oncological results at 3 years (medium-term) comparable with those for the laparoscopic and open approaches. Better monitoring is required with studies of the long-term functional and quality of life outcomes, i.e., at 5 or 10 years.

Vertebral fractures are increased in rheumatoid arthritis despite recent therapeutic advances: a case-control study.

Prevalence and risk factors of vertebral fractures in postmenopausal RA women were assessed in 323 patients and compared with 660 age-matched women. Of patients, 24.15% had at least one vertebral fracture vs.16.06% of controls. Age, glucocorticoids and falls were the main fracture risks. Vertebral fractures were associated with disease severity. INTRODUCTION: There is little quality data on the updated prevalence of fractures in rheumatoid arthritis (RA) that may have changed due to advances in the therapeutic strategy in recent years. This study was aimed at analysing the prevalence and risk factors of vertebral fractures in postmenopausal women with RA and comparing it with that of the general population. METHODS: We included 323 postmenopausal women diagnosed with RA from 19 Spanish Rheumatology Departments, randomly selected and recruited in 2018. Lateral radiographs of the thoracic and lumbar spine were obtained to evaluate morphometric vertebral fractures and the spinal deformity index. We analysed subject characteristics, factors related to RA, and fracture risk factors. The control group consisted of 660 age-matched Spanish postmenopausal women from the population-based Camargo cohort. RESULTS: Seventy-eight (24.15%) RA patients had at least one vertebral fracture. RA patients had increased fracture risk compared with controls (106 of 660, 16.06%) (p = 0.02). Logistic regression analysis showed that age (OR 2.17; 95% CI 1.27-4.00), glucocorticoids (OR 3.83; 95% CI 1.32-14.09) and falls (OR 3.57; 95% CI 1.91-6.86) were the independent predictors of vertebral fractures in RA patients. The subgroup with vertebral fractures had higher disease activity (DAS28: 3.15 vs. 2.78, p = 0.038) and disability (HAQ: 0.96 vs. 0.63, p = 0.049), as compared with those without vertebral fractures. CONCLUSION: The risk of vertebral fracture in RA is still high in recent years, when compared with the general population. The key determinants of fracture risk are age, glucocorticoids and falls. Patients with vertebral fractures have a more severe RA.

[Efficacy of magnetotherapy in hand erosive osteoarthritis. A clinical trial]. / Eficacia de la magnetoterapia en artrosis erosiva de manos. Un ensayo clínico.

INTRODUCTION: Erosive arthritis is an unusual pathology. Despite using magnetotherapy as a treatment, there is no evidence supporting its use. The aim of the study is to evaluate magnetotherapy efficacy in patients suffering from hand erosive arthritis, compared to placebo, in terms of pain. Treatment safety will be also evaluated. METHOD: Prospective experimental double-blind randomized study consisting of an intervention group (IG: treatment with magnetotherapy: 15 20-minute-sesions 5 consecutive days per week) and a control group (CG: placebo). Treatment efficacy was evaluated at the end and 3 months after. We used Visual Analog Scale (VAS) for assess pain. Secondarily, functionality (The Disabilities of the Arm, Shoulder and Hand (DASH) score), rigidity (Modified Kapandji Index), grip strength (dynamometry) and quality of life (SF-36 questionnaire) were assessed. RESULTS: 29 patients were evaluated. Due to exclusion criteria, there were 19 patients left, all women with an average age of 59. After randomization, 10 were awarded to IG and 9 to CG, being both comparable groups. A higher percentage of patients with pain controlled (VAS<6) was found in IG post treatment and after 3-months (77.8% vs 33.3%, p=0.1 y 83.3% vs 33.3%, p=0.2; respectively). A tendency to decrease VAS for IG at 3-months (regression coefficient: -2.1 (95% CI: -5.7-1.5; p=0.2) was showed. There were no other statistically significant differences, except a higher dynamometry results in IG, in both hands (p<0.01 and p<0.04 respectively). There were neither adverse effects nor secondary effects. CONCLUSION: Magnetotherapy treatment for hand erosive arthritis patients is safe and probably leads to clinical improvement.

Reproduction of the blue-spotted maskray Neotrygon kuhlii (Myliobatoidei: Dasyatidae) in south-east Queensland, Australia.

This study examined the reproduction and population structure of the blue-spotted maskray Neotrygon kuhlii within Moreton Bay, a subtropical embayment in south-east Queensland, Australia. Mean sizes at maturity were 314 mm disc width (W(D)) in females (n = 140, 115-465 mm W(D)) and 294 mm W(D) in males (n = 123, 129-381 mm W(D)). Female N. kuhlii had a synchronous annual reproductive cycle, with one litter of one to three pups (mean +/-s.d. 1.67 +/- 0.71) produced per year. Mating behaviours were observed in October and November, and ovulation occurred early in the Austral summer, overlapping with the start of embryonic development. Gestation took c. 4 months with parturition occurring in late February and March. Size at birth was 115-170 mm W(D). The population showed a significant female bias, particularly in larger size classes. Tagging studies produced a total recapture rate of 16.1% and indicated that N. kuhlii were site resident for up to 1081 days.

Intensive dietary intervention promoting the Mediterranean diet in people with high cardiometabolic risk: a non-randomized study.

AIMS: Mediterranean diet (MD) is acknowledged to exert a number of beneficial health effects. We assessed the efficacy and the durability of a 3-month intensive dietary intervention aimed at implementing the MD on body weight and cardiometabolic risk factors in subjects at high risk. METHODS: One hundred and sixteen subjects participated in the study (71 assigned to the intensive intervention and 45 to the conventional intervention). The intensive intervention consisted of 12 weekly group educational meetings and a free-of-charge supply of meals prepared according to the MD model. The conventional intervention consisted of an individual education session along with monthly reinforcements of nutritional messages by the general practitioner. All participants were followed up for 9 months. RESULTS: The two groups had similar pre-intervention characteristics. After the intervention, mean body weight decreased significantly in both groups (p < 0.001). However, the intervention group lost more weight (6.8 ± 4.0 vs. 0.7 ± 1.3, p < 0.0001) and showed a greater reduction in plasma glucose, triglycerides, blood pressure and an increase in HDL cholesterol than the control group (p < 0.01-p < 0.002). In the subgroup of participants with type 2 diabetes, there was a significant reduction in HbA1c level following the intensive (p < 0.0001) but not the conventional intervention. At follow-up, weight loss still persisted in the intervention group (p < 0.0001), while it was lost in the control group. Both interventions significantly reduced blood pressure in the long term (p < 0.001). A significant reduction in daily total energy intake was observed in both groups with a greater reduction in saturated fat and a higher increase in fibre intake in the intervention than in the control group (p < 0.009 and p < 0.001, respectively). CONCLUSIONS: A 3-month intensive dietary intervention inspired to the traditional MD produced greater and more durable weight loss and improvement in cardiometabolic risk profile than the conventional intervention.

Induction Immunosuppressive Therapy Use in Deceased Donor Kidney Transplantation: 11-Year Experience in Veracruz, Mexico.

BACKGROUND: Induction therapy reduces the frequency of acute rejection and delayed graft function in renal transplantation. Basiliximab and Thymoglobulin are most commonly used agents for induction. METHODS: A retrospective study of two transplant centers in Veracruz, Mexico compared induction therapy in deceased donor renal transplantation from 2003 to 2014. Efficacy and safety outcomes evaluated were primary graft nonfunction, delayed graft function, acute rejection episodes and hospitalizations during first year, and patient and graft survival. P < .05 was considered statistically significant. RESULTS: Seventy deceased kidney donors (40 male) were studied. Mean donor age was 32.9 ± 14.3 years, mean donor BMI 25.6 ± 4.3 kg/m(2), and mean donor creatinine 1.13 ± 0.58 mg/dL. Main cause of death was trauma (62.9%). In total, 125 kidney transplantations were performed, with female predominance (53.6%) and mean age 33.8 ± 11.8 years. Of these, 66.4% used basiliximab and 33.6% Thymoglobulin. Thymoglobulin patients were significantly older, with lower weight and BMI, and were on dialysis longer than basiliximab patients. DGF was present in 19.3% of basiliximab patients vs 16.7% in Thymoglobulin patients, acute rejection occurred in 16.9% of basiliximab patients vs 19% Thymoglobulin patients. A total of 33.7% basiliximab patients were hospitalized during the first year vs 47.6% Thymoglobulin-induced patients (P > .05). Mean graft survival was 84.2 ± 5.3 months (73.8-94.7) basiliximab vs 32.4 ± 28.7 months (28.7-36.1) Thymoglobulin, Kaplan-Meier survival did not show statistically significant differences between groups (P = .276; CI 95%). CONCLUSION: Similar transplant outcomes were obtained using basiliximab or Thymoglobulin induction in our population.

A new consensus error grid to evaluate the clinical significance of inaccuracies in the measurement of blood glucose.

OBJECTIVE: The objectives of this study were 1) to construct new error grids (EGs) for blood glucose (BG) self-monitoring by using the expertise of a large panel of clinicians and 2) to use the new EGs to evaluate the accuracy of BG measurements made by patients. RESEARCH DESIGN AND METHODS: To construct new EGs for type 1 and type 2 diabetic patients, a total of 100 experts of diabetes were asked to assign any error in BG measurement to 1 of 5 risk categories. We used these EGs to evaluate the accuracy of self-monitoring of blood glucose (SMBG) levels in 152 diabetic patients. The SMBG data were used to compare the new type 1 diabetes EG with a traditional EG. RESULTS: Both the type 1 and type 2 diabetes EGs divide the risk plane into 8 concentric zones with no discontinuities. The new EGs are similar to each other, but they differ from the traditional EG in several significant ways. When used to evaluate a data set of measurements made by a sample of patients experienced in SMBG, the new type 1 diabetes EG rated 98.6% of their measurements as clinically acceptable, compared with 95% for the traditional EG. CONCLUSIONS: The consensus EGs furnish a new tool for evaluating errors in the measurement of BG for patients with type 1 and type 2 diabetes.

Role of injection technique in use of insulin pens: prospective evaluation of a 31-gauge, 8-mm insulin pen needle.

OBJECTIVE: To evaluate the effectiveness, comfort, and ease of use of insulin pen injections with a 31-gauge, 8-mm needle. METHODS: In 50 study subjects (24 patients with type 1 insulin-dependent diabetes and 26 insulin-using patients with type 2 diabetes), we assessed the delivery of insulin, residual insulin leakage, glycemic control, plunger depression pressure, and perceived pain associated with the B-D 31-gauge, 8-mm pen needles in comparison with the B-D conventional 30-gauge, 8-mm pen needles, while the patient used their own insulin pens (Novo or B-D). The study subjects injected their usual dose of regular and NPH insulin using the 30-gauge, 8-mm needle during the first 3 weeks of the study. This period was followed by two 3-week crossover segments of the study with either needle assigned in random sequence. RESULTS: No statistically significant differences were noted in glycemic control or perceived pain of injection between the two needles. The interaction between the two needles and the two insulin pen brands on glycemic control was not statistically significant. Plunger depression pressure increased with the increase in the gauge of the needle and with increases in size of dose of injected insulin (P<0.01). B-D pen users reported lower plunger pressure ratings in comparison with Novo pen users (P<0.01), regardless of the needle type and dose range. Both the insulin pen type and the needle type individually had statistically significant (P<0.01) effects on the residual insulin leakage from the needle tip after injection; however, their interaction was not statistically significant. Insulin doses greater than 30 units were associated with increased leakage (P<0.01). As needle retention time decreased, residual insulin leakage from the needle tip after injection increased (P<0.01), regardless of the needle used. CONCLUSION: The 31-gauge insulin pen needles are safe and effective for the delivery of insulin. With both 30-gauge and 31-gauge needles, attention to injection technique is essential to ensure complete delivery of insulin, particularly with administration of large doses.

[Syphilitic arthro-osteitis]. / Artroosteítis luética.

We report a black female with past history of sexual promiscuity who developed arthroosteitis of clavicula and sternoclavicular joint and cranial osteitis during secondary syphilis. Spirochaeta were identified in the material from osteoarticular biopsy. The patient was treated with benzathine penicillin, 2,400,000 U weekly for three weeks. There was a complete clinical recovery. We emphasize the uncommon occurrence of osteoarticular involvement in secondary syphilis and the exceptional character, according to the literature, of the finding of spirochaeta in the biopsy material. We discuss the differential diagnosis and we review the literature on secondary syphilis. We suggest that syphilis should be considered in the differential diagnosis of any acute arthritis or osteitis, particularly when the involved joint is the sternoclavicular and the patient is sexually promiscuous.

[Risk factors related to esophageal cancer in Rio Grande do Sul, Brazil]. / Fatores de risco relacionados ao câncer de esôfago no Rio Grande do Sul.

BACKGROUND: Rio Grande do Sul, a State in southern Brazil, shows high mortality rates for esophageal cancer. Important geographical variations suggest external factors in the etiology. OBJECTIVE: The relationship between smoking, alcohol and "mate" to esophageal cancer. METHOD: 55 patients with esophageal cancer were interviewed, soon after the endoscopy, about risk factors; 110 patients who did not showed esophageal tumor in the endoscopy were the controls. RESULTS: Among the patients with esophageal cancer there were more farmer-workers (OD 3.3; 95% CI 0.9-11.2), father with antecedent cancer (OD 6.9; 95% CI 1.9-25.6), smoking and ex-smoking (OD 2.5; 95% CI 1.1-5.9), drinkers and ex- of alcohol (OD 5.3; 95% CI 2.6-11.0), drinkers and ex- of "mate" (OD 3.6; 95% CI 1.3-9.8). Others variables more frequent in the cases were: smoking for > 20 years; kind of alcohol (spirits), drinking alcohol every day, drinking "mate" every day and adding salt to food. CONCLUSIONS: Smoking, alcohol, "mate", farmer-workers and antecedent of father with cancer were significantly more frequent in the cases of esophageal cancer than in the controls.

Rejection is a strong graft survival predictor in live donor pediatric renal transplantation using cyclosporine, mycophenolate mofetil, and steroids: 5-year outcomes in a single Mexican center.

Long-term graft function and survival are of particular importance in children assuming that they have a longer transplantation life span than most adults. Because acute rejection episodes (ARE) continue to have a serious impact on graft loss, we analyzed the effects of ARE on 5-year survival and function in our population. Fifty-seven living donor kidney transplant recipients (34 males) younger than 18 years of age (13.5 ± 2.6 years; range, 5-17) were follow up for at feast 12 months using cyclosporine, mycophenolate mofetil, and steroid therapy with or without induction treatment between February 2003 and December 2010. ARE incidence during the first 12 months following transplantation was 14%. One-, 3- and 5-year serum creatinine values were 1.24 ± 0.39, 2.16 ± 2.39, and 1.76 ± 0.9 mg/dL, respectively. Mean calculated creatinine clearances (Schwartz) at 1, 3, and 5 years were 82.5 ± 24.8, 64.7 ± 24.1, and 67 ± 27.5 mL/min*1.73 m(2), respectively. Patient/graft survival rates were 96/85%, 90/72%, and 88/65% at 1, 3, and 5 years, respectively. Patients who experienced an ARE within 12 months following transplantation displayed a reduced 5-year graft survival rate (37.5%) versus those who did not (78%; P = .005). Patients who did not have an ARE during 60 months had a higher graft survival rate (76%) than those who had ARE (33%; P = .001). Patient without basiliximab induction showed a lower 5-year graft survival rate (61% vs 100%; P = not significant [NS]). ARE is an important risk factor for graft loss in the pediatric kidney transplant population.

Labioplastía genital, experiencia y resultados en 500 casos consecutivos / Genital labiaplasty, experience and results in 500 consecutive cases

ANTECEDENTES: La cosmetoginecología se ha instalado, no exenta de controversia, en la práctica ginecológica durante la última década. OBJETIVO: Presentar los resultados obtenidos en una serie de 500 labioplas-tías de labios menores realizadas por dos cirujanos en el curso de 10 años. MÉTODO: Estudio descriptivo del universo de labiobioplastías practicadas por dos cirujanos entre octubre de 2003 y abril de 2014. La decisión de intervención quirúrgica se basó en razones estéticas, funcionales y psicológicas, y no por una clasificación de hipertrofia de labios menores. RESULTADOS: Aproximadamente la mitad se realizó utilizando láser y la otra mitad electrobisturí, sin ventajas de alguna técnica sobre la otra, en cuanto a complicaciones, grado de satisfacción y resultado final estético. Las indicaciones fueron: estética en 95,4% de las intervenciones, funcional en 37,2% y psicológicas en 17,4%. Los resultados fueron satisfactorios en el 99% de las pacientes, según un autoreporte. No hubo complicaciones importantes y sólo en dos casos se presentó hemorragia post operatoria que requirió una sutura. El procedimiento, cuando fue único, fue ambulatorio, requiriendo no más de 8 horas de hospitalización. En esta experiencia, el 46% se asoció a otra cirugía ginecológica. CONCLUSIÓN: A nuestro parecer, la hipertrofia de labios menores, aún cuando pueda considerarse subjetiva, es una condición que merece ser corregida cuando es requerido por la paciente y que las técnicas actuales ofrecen resultados seguros y satisfactorios.

BACKGROUND: Cosmetogynecology is installed, not without controversy, in gynecological practice in the last decade. Aims: We present a descriptive study of 500 labia minora labiaplasty performed by two surgeons in the course of 10 years. METHOD: A descriptive study of the universe of labiobioplastys performed by two surgeons between October 2003 and April 2014. The decision for surgery was based on aesthetic, functional and psychological reasons and not on a classification of labia minora hypertrophy. RESULTS: Approximately, half was performed using laser, and electrocautery the other half, without any technical advantages over the other, in terms of complications, satisfaction and aesthetic final outcome. Indications for surgery were: in 95.4% of interventions, functional in 37.2% and 17.4% psychological. The results were satisfactory in 99% of patients, according to a self-report. There were no major complications and only two cases presented postoperative bleeding that required stitches. The procedure was ambulatory when it was unique, requiring no more than 8 hours of hospitalization. In this experience, 46% was associated with another gynecological surgery. CONCLUSION: In our view, the labia minora hypertrophy, even though it may be considered subjective, is a condition that should be corrected as required by the patient and the current techniques provide safe and satisfactory results.

Successful renal transplantation from a deceased donor with pesticide intoxication: a case report.

The number of individuals awaiting organ transplantation exceeds the number of organs. Patients who die from intoxication are rarely accepted as potential organ donors. Herein we have presented the results of kidney transplantations performed from a deceased 20-year-old female donor with suicidal ingestion of a pesticide (carbamate). The procured kidneys were successfully transplanted. Patients and grafts are doing well at 4 months following transplantation. There are few reports of successful transplantation of organs obtained from patients who die from various intoxications. Poisoned patients represent another pool of organ donors for transplantation services.

[How to identify adverse events in emergency services? A guide agreed for the screening]. / ¿Cómo identificar los efectos adversos en urgencias? Una guía consensuada para el cribado.

OBJECTIVE: Since a third of adverse events (AE) occur outside hospital, the Emergency Services are a suitable place to look at their incidence. We considered designing a screening guide, adapted to the conditions of the emergency services, to identify AE. MATERIAL AND METHODS: A qualitative technique was applied (nominal group) in which 14 professionals participated. They analysed which factors of intrinsic risk, extrinsic risk, and alert conditions, were suitable for a screening guide of AE in emergency services. The session was chaired by a specialist in these types of techniques. RESULTS: Consensus was high in that the most frequent AE in emergencies were those related to medicines, diagnostic tests and with the correct identification of the reason for emergency. With respect to screening guide, the group proposed adding alcohol abuse, patient social problems, cognitive deterioration, basal autonomy and disability. In relation to extrinsic risk factors, they pointed to the need of including defibrillation, spinal tap or drainage implantation. With respect to the alert conditions form, the professionals agreed in that all the criteria seemed correct and suitable, except for that related to damage relation childbirth or amniocentesis. CONCLUSIONS: By using this technique we have managed to validate materials already recognized, and widely used in our country. The screening guide was considered useful, with slight modifications in some risk factors and alert conditions. The professionals agreed that the MRF2 modular questionnaire is appropriate for the characterisation of AE in emergencies.
